Closed Captioning

Types of Closed Captions

Roll-up Captions

Are you looking for live television broadcasting?

Without a second thought, use roll-up captions as they are most commonly in live programming. Roll-up captions scroll up two to three lines at a time and are either from the top or bottom of the screen. Then the top line disappears off the screen to make room for a new line that continuously rolls up in sync with the audio. These captions are always verbatim, and using accurate grammar or punctuation is not necessary. Apart from live captioning, roll-up captions are sometimes preferred in pre-recorded videos where there is a single speaker in educational videos or when narrating documentaries.

Pop-on Captions

Would you like to create accessible videos to reach a bigger audience?

If yes, prefer pop-on style closed captions. Pop-on captions are exclusively used for pre-recorded videos and appear in blocks of one to three lines at a time. This set of captions are then replaced by a new set such that the text and audio are synchronized. These captions include all the on-screen text or information with speaker identification, accurate grammar, and spelling. This style also includes sound effects and other non-speech noises. Pop-on captions are more time-synchronized, accurate, and descriptive.
